More energy efficient home = less durable

In this new episode, our hosts Reuben Saltzman and Tessa Murry discuss the intricate relationship between energy efficiency and durability in home construction. They explore how increasing energy efficiency through insulation and air sealing can lead to potential moisture issues and reduced durability if not appropriately managed. The conversation emphasizes the importance of understanding house systems and the need for a holistic approach to building performance, especially in changing climate conditions and homeowner expectations.
